# Create an updated version of the Rectangle class from activity1/task2 with the following methods:
# (1) area method to return the area of a rectangle
# (2) perimeter method to return the perimeter of a rectangle






# Once completed, create 2 instances of Rectangles with:
# (1) first rectangle with width = 4 and height = 40
# (2) second rectangle with width = 3.5 and height=35.9
# After that, print the area and perimeter of both rectangle instances.




# Did you have setters with validation? Can the value of width and height be negative?
# If you have not, update the setters with validation for the width and height.
